PROBLEM TO BE SOLVED: To provide an image measuring camera by which the three-dimensional shape of an object to be measured can be acquired with high accuracy. SOLUTION: A light source projects measuring line pattern light extended to a prescribed direction, onto the object to be measured. A photodetector array detects the line pattern light reflected by the object to be measured. The photodetector array is arranged in such a way that its row direction as its transfer direction becomes parallel to the line pattern light. Output signals transferred sequentially from photodetectors belonging to each row of the photodetector array are analog-to-digital-converted by a corresponding A/D converter. A zero-order moment computing unit and a first-order moment computing unit find a zero-order moment and a first-order moment in a direction perpendicular to a direction in which the line pattern light is extended in respective positions in the direction, in such a way that digital signals corresponding to the output signals obtained in nearly the same time by the photodetector array are integrated.
